To @all whom if; may concern:

Be it known that l, Srrnson E. TROTT, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented cert-ain new and useful Improvements iu Paper Pressed Shinglee; and l do hereby declare the following to be a tulLelear, and enact description of the invention, such as will enable others skilled in the art to which it. appertains to makeand use the same. Y

My invention relates to an improvement in peper pressed shingles. Zlhe objeet isto provide a shingle which v shall be impervious'to moisture, very durable,

and which will retain its place without warp` ing when exposed to the weather.

i further object is to provide ay shingle of the above character which may be furnished at a, very low cost.

Vtith these ends in View my invention oo nsists in certain tentures of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.

ln the accompanying drawings, Figure l represents one forni ot press which l find it convenient to employ in the construction of my improved shingle. lFig. 2 represents piece of shingle ot uniform thickness. Fig. 3 represents o plan View of my improved shingle, and Fig. It represents an enlarged longitudinol transverse section of the same.

The materiel which composes the shingle consists of straw-board or other cheap ibrous substance thoroughly coated with a mixture of rubber, asphalltlum, lend sulphur, the three ingredients of the mixture being melted together and introduced in such proportions as may be found expedientto produce the best results. Cool-tor might also be used as a coating. rlhe surfe-ees of the straw-board or other tibi-ous materiel after having been saturated with the liquid mixture named are covered with it layer of fine sand,which,because of the adhesiveness of the liquid mixture, is re tained in position on the surfaces ot thc shingle until the same is submitted to pressure. After treating the shingle as above indicated, it is submitted to strong hydraulic or other pressure between surfaces one or both ot' which are heated to such a degree as to cardressing to become thoroughly incorporated with the carbonized material which covers the surface ot' the board, so that it will not be liable to be washed away by heavy rains. The sand-dressing is particularly Valuable as a preventive against warping or curling of the exposed boards or shingles, au objection which has heretofore prevailed, and to render it reproof.

In the accompanying dra-wings l have represented a simple form of press consisting of tho bed-plate A suitably supported upon standards o, and heated to the proper degree by means of a scri es of gas-j or other direct heat issuing t rom nipples arranged in a group or series on the supply-pipe B, located beneath the bed-plate. The movable platen C of the press is supported to slide toward and away from the bed-plate A, and is actuated in the present instance by hydraulic pressure, the liquid being admitted into the cylinder above the movable platen through the pipe c, which leads to a suitable force-pump or other device for forcing the liquid into the cylinder.

The piece of shingle ot' uniform thickness is represented by the letter I), and in the form herein shown it consists of a single thickness only of the straw-board orother ibrous material saturated with the mixture, as hereinbefore set forth, and pressed and carbonized. In a shingle, however, where it is desired that there should be a taper in the thickness t'rom the butt to the top I find it expedient to form the piece of shingle four-ply, (represented by the letters I) D D2 D3.) In o shingle fourteen inches long, for example, this four-ply would extend for a distance of scvcn inches, or thereabout, from the butt, then thc next three and one-half inches would be made three-ply, one of thc layers, D2, being omitted, and the balance of the shingle or the last three aud onu-halt' inches at the top would bc made two-ply, thc layer D being omitted, The several plies are tirst united by in ucilage or otherl common adhesive. As thus com structed, the blank is saturated with the solution, dressed with sand, and submitted to a ICO strong pressure and the earbonizing process', which reduces the Whole into a hard, compact', and practically indestructible shingle having the taper of a saWed shingle and capable of being applied to the roof infthe same manner as the ordinary shingle.

It is obvious that the number of layers or ply employed in the construction of either the shingle of uniform thickness or the shingle with its tapered form is a matter of judgment and may be changed to suit the requirements of any particular case.

Having thus fully described my invention, 'what I claim as new, and desire to secure by Letters Patent, is

1. The herein-described covering material, consisting, essentially, of a fibrous base saturated With a mixture of rubber, asphaltum, and sulphur,having a surface dressing of sand, the said saturated and dressed material being pressed into shape and carbonized,substantially as set forth.

2. A pressed shingle composed of a fibrous base treated with rubber, asphaltum, and sulphur and carbonized, substantially as set forth.

3. A pressed shingle having a greater num ber of layers of fibrous material at its butt than at its top, substantially as set forth.

4. A pressed shingle having a greater number of layers of fibrous materia-l at its butt than at its top, the said fibrous material being treated with rubber, asphaltum, and sulphur and carbonized, substantially as set forth.

5. A pressed shingle consisting of a fibrous base tapered from the butt toward the top, the said base being treated With rubber, asphaltum, sulphur, and sand, substantially as set forth.

6. A pressed shingle composed of a fibrous base treated with rubber, asphaltum, sulphur, and sand and carbonized, substantially as set forth. 1

7. As an article of manufacture, a paper shingle having a greater number of' layers of paper at its butt than at its top. 4

In testimony whereofJ have affixed my signature in presence of two Witnesses. I
